There are currently no clinically available inhibitors of metallo-β-lactamases (MBLs). These enzymes confer resistance to bacteria against a broad range of commonly used β-lactam antibiotics, and are produced by an increasing number of bacterial pathogens. In this study, several thiol derivatives of l-amino acids were designed and synthesized, and their inhibitory effects against the metallo-β-lactamase
The synthesis and structure-activity relationship of a series of mercaptoacylamino acids are described. These compounds were tested for antihypertensive activity. When the compounds were screened as angiotensin I-converting enzyme inhibitors in vitro, N-(2-mercaptopropanoyl)-L-cysteine-a (7a) and N2-(2-mercaptopropanoyl)-L-tryptophan-a (20a) were found to be 10 and 20 times more active than tiopronin, respectively.
本文描述了一系列巯基氨基酸的合成和结构-活性关系。对这些化合物进行了抗高血压活性测试。在将这些化合物作为血管紧张素 I 转换酶抑制剂进行体外筛选时,发现 N-(2-巯基丙酰基)-L-半胱氨酸-a(7a)和 N2-(2-巯基丙酰基)-L-色氨酸-a(20a)的活性分别是硫普罗宁的 10 倍和 20 倍。
